Hello,
I have an old Lenovo B580 with 4gb or ram, i3 CPU and 5400rpm HD and its way to slow to use.
Its fairly easy to upgrade the ram and add an SSD what i don’t know is the actual max CPU that it will support.
The manual at page 85:
https://download.lenovo.com/pccbbs/mobil…b580_hmm_en.pdf
States that the max cpu is the i5-3210M Ivy Bridge L-0 3MB 2c PGA 2.5GHz STD 35W processor
On the other hand the motherboard uses the chipset HM77 so a quick search online:
http://www.cpu-upgrade.com/mb-Intel_(chi…77_Express.html
and i found that the chipset supports up to quad core i7
Could it be that the laptop does support i7 processors but Lenovo didn’t test the laptop with them so that’s why it didn’t include them in the support list ?
I have encountered that scenario before it wont be the 1st time.
what are my chances that an i7 cpu with work ? I used MC extractor to get the microcodes supported by the bios should I trust the findings ?
Can someone please verify the microcodes, so i know my findings are correct ?

Thank you

@Biomecanoid Your microcodes are mostly Core2duo ones and don’t seem to fit to the rest of your post. Anyway: With notebook eveything is possible. There might be a whitelist in the bios, tdp of new cpu might be too high (quad-core is 45W- that’s not only relevant for the fan/ cpu temperature but also for the voltage regulators…), soldered cpu…
If it’s really an Ivy Bridge board: With an SSD and a little more ram you’d possibly be happy. Difference between i5 and i7 is neglectable compared to changing from 5400 rpm HD to SSD. But changing from SNB i3 to IVB i5 cpu might be worth it…
Microcode for SNB 206A7, for IVB 306A9
Thank you for the reply. I posted here so you can correct me. So can you please match the microcodes with actual cpu models for me ?. The 306A9 is Core i7-3770S right ?
I guess I should open up the laptop again to verify if the cpu is in a socket or not.
What is the max cpu you suggest for my case or what info do you need to help me determine that ?
CPU is indeed removable and not soldered on, just verified it
You are right i posted the wrong codes by mistake. These are the correct ones :

You probably could go for some i7**QM cpu.
I mean your laptop can handle 45W TDP but the question is, if the throotling is in action, you might not enjoy max multiplier.
On the other hand ivy bridge is better then Haswell with regards of throotling, so it is up to you.
My manual for old crap Lenovo B320 even didn’t mentioned i7 cpus, but I took the risk and it worked out.
